(or. 119- 303) This inventionuelates to new and useful improvements in supports and ad iuatments for lens combinations in moving picture apparatus, and has particular reference to supports and adjustments for lens combinations which are usedin connection with talkingr-movie apparatus for the purpose of transforming sound striata on the film into sound impulses.

A main object of theinvention is to provide a simple, compact, durable,and accurately adjustable support for such a lens combination.

A turther object is to provide a simple, compact. and readily operable device which can be adjusted and manipulated with the leasteinxandi ture of time and eifort on the-part or the operator.

A still further object is to provide a simple. compact, and accurate device that altho it is simple, and easily, andreadily, and accurately adjustable as above mentioned, the entire unit is supported and held even during adjustment, inabsolute alinement and rigidly in relation to the parts with motion with the accompanying'drawings which term part 0! the specification and which illustrate one present preferred form 0! the invention.

Briefly and considered in its broadest aspects the invention contemplates -mounting thexlens combination or the sound assembly on a talkingmovie apparatus in ready and adjustable relation to the exciter lamp of the assemblyas well as in operable'relation to the light'sensitivenell which is usually employed in such assemblies.

To this .end the lens combination is securely fastened in clamping members which are'in turn adiustably and slidably fastened to suitable spaced supports such as spaced rods or bars disposed securely on the mechimism-supporting wall or partition of the projection head of themachine.

The lens combination thus supported is provided with a simple adjusting knob provided with means engaging one or moreof the supporting elements so that as the knob is manipulated the lens combination unit can be readily moved to or from the exciter lamp or the light sensitive cell as may be desired. The lens combination unit is also, during its movement and at all times, constructively associated with certain light shielding means sothat no matter what position it is is a side elevation of that sidoofthe ass mb y: which it co-operates and so securely and rigidly unitl shutter guard casing G, and film H.

caused to assume the. light from the exciter lamp D 8 1112, therethrough will be efliciently and properly enclosed. The shields are also construotivflb' related to and associated with the usual film gate which is fixed to the supports adjacent the lens 60 combination unit in such manner that all the light thus shielded properlypasses through the gate to, the film and the construction is such as to permit the quick and readyadiustment or the ions combinationwhile shielding the light and 66 7 without disturbing the position of thegate itself .onaccount of the movement of the lens combina- .tion.

The present preferred form-of the invention is illustrated as applied to a motion picture machine in which the projection oi pictures in motion is with the production of synchro- 96 nous and related soun erwise known as talking movie projectors. It is particularly illustrated in a form of such machine for portability in the term of asuit case projector.

and entitled Supportandadjustment for speakt,

wall 10 which is common in modern projectors.

The unit is supported from preferably two spaced rods 11 and 12 which extend horizontally along the one side of the wall 10 and are fastened thereto by means of brackets such as 13, 14, and

1.5. Adjacent the bracket 13 there is disposed an I exciter lamp 16 adjustably mounted on a support 17 which is slidable along the rods 11 and 12. The manner of the adjustment and manipulation of the lamp 16 is shown and'described and claimed in the above mentioned Patent No. 1,863,300. This adjustment is effected by manipu-. lation of the adjusting screws 18, 19, and 20.

Adjacent the exciter lamp is disposed the lens combination unit F, thus designated in Fig. 1. Thisunit as far as this invention is concerned,

comprises a lens combination element or casing 21 which may be of any suitable type and contain any desired combination of lenses for the purpose in view. This element 21 is firmly supported pref erably in a horizontal position in spaced collars 22 and 23 into which the element 21 snugly fits.

The collars 22 and 23 are respectively provided with inwardly extending horizontalarms 24 and 25 having intermediate sleeves 26 and 27 bored to receive an elongated bolt 28, the nuts 29 and 30 on the ends of which cause it to hold the arms and hubs tightly together. The inner ends of the arms 24 and 25 are connected. preferably integrally to upright plates 31 and 32 which respec:- tively have collars 33, 34, and 35,36 at their upper and lower portions. These collars 33, 34 and 35, 36 are bored to receive the rods 11-- and 12.

One of the platessuch as 31 is vertically bored to receive an operating shaft 37 having an upper operating knob 38 and provided with teeth 39 and 40 engaging with teeth 41 and 42 on the rods 11 and 12. The turning of' the knob 38 willthen cause the movement of the lenscombination unit along the rods 11 and 12 and the fit of the parts and the friction thereof is such that when adjusted in one position they will stay there indefinitely.

To a face of the sleeve 2'7 there is fastened a thin shield plate 43 which extends towardthe collar 23 and in line with the opening-therein is formed in the shape of preferably integral sleeves 44 and 45 of successively smaller diameter axially alined with the axis of the lenses in the lens combination element 21. is adapted to slide back and forth with the'move- The smaller sleeve 45 ment of the support and is telescopically related to a similar and in th's case smaller shielding sleeve 46 which is fixed to the rear face of .the i sound film gate plate 47.

This sound film gate plate 47 is supported on the bracket-member 15 and has collars 48 and 49'which surround the rods 11 and 12; The collars 48 and 49 are provided with set screws 50 and 51 whereby they may be set on the rods 11 and 12 as desired.

The film gate plate 47 is in'the usual manner related and disposed adjacent to the film gate plate door 52which is supported on the rods 11 a manner such as set forth in my above mentioned Patent No. 1,847,643.

The collars 22 and 23 are preferably made in two pieces which can be held together by means of set screws such as 55 and 56 so that it is an easy matter to insert the lens combination element 21 into position.

It will therefore be observed that this inventib'n provides a simple compact and easily adjustable lens combination unit for the sound reproducing assembly of a talking-movie machine. The simple support on the wall 10 acts to support not only the exciter lamp and the light-sensitive cell, but also the, adjustable lens combination. The combination can bemanipulated with a slight movement of a finger to adjust it with respect to the exciter lamp and with respect to the fixed film gate; The exciter lamp can also be regulated and adjusted in a variety of directions by simple V mechanism.

While the invention has been described in detail and with respectto-a present preferred form thereof, it is not to be limited to such details and forms since many changes and modifications may be made and the invention embodied in other forms and modifications'without departing from the spirit and scope of the invention when consideredin its broadest aspects. Hence it is desired to'cover any and all forms and modifications of the invention which may come within the language or scope of anyone or more of the appended claims.
